Working Principles

The DRV10963JMDSNT is a three-phase brushless DC motor driver that utilizes sensorless commutation. It operates by monitoring the back electromotive force (EMF) generated by the motor windings to determine the rotor position. This information is used to drive the motor phases in the correct sequence, resulting in smooth and efficient motor operation.

The motor speed can be controlled using either open-loop or closed-loop techniques. In open-loop mode, the motor speed is set by applying a PWM signal to the PWM pin. In closed-loop mode, the motor speed is regulated based on the feedback received from the FG pin, which provides information about the actual motor speed.
